Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi I was using ubuntu 10.04 and tvtime was working perfectly. But after I upgared it to 10.10, I cannot adjust the volume. The Volume shows zero. There is no sound at all. The right arrow key is not increasing the volume. I tried many ways but to no avail. Does anyone have a solution for this. Thanx in advance.

Depending on your TV card, volume may have a different hardware control. Mine uses line in. Sound Preferences, Hardware tab may show two devices, make sure the TV isn't off. This may not be your problem but worth mentioning here. Comcast upgraded basic TV service and an adapter box is required. With that box, TV volume is controlled by the box and the remote that came with it. Changing volume on the computer has no effect on volume with this Comcast service.

Welcome, new recruit to Linux sound wars, which don't seem to ever end. What TV card do you have? Do you have a mixer app and does it show any inputs muted? Mixer apps seem to have gone away in stock Ubuntu distributions so you may need to install one. Otherwise the command line "alsamixer --view all" may help.

Hi Kenarkies, I installed all the alsa packages using synaptic but to no avail. I have the Phillips saa7134 card. It was working fine in ubuntu 10.04 though I had to modprobe the card as "modprobe saa7134 card=81 tuner=51 alsa=1". I don't know how to get the sound.

I have the same problem. I've used tvtime since 9.10 perfectly, when I used it with Maverick the volume just won't move from 0 no matter what I do.

The DMA drivers are loaded, my Ubuntu sound is working for everything else. And on 'Sound preferences' the input meter detects sound from the tv card (I use Line in from the tv card to the main soundcard). So the problem is that tvtime just doesn't want to have its volume increased hence I can't listen to tv programs.

I can watch tv fine. So the problem is that tvtime just doesn't want to have its volume increased hence I can't listen to tv programs.

Ubuntu has that file but I believe it's use is only for running tvtime the first time. It's comments are of great value but I believe the file you wish to change is ~/.tvtime/tvtime.xml in your home folder.

Hi fellow Ubuntu users,
The answer to the problem isn't hard as you're making it. I spent a few hours fiddling with the different setup files without success. TVTime worked fine for me in 8.04 LTS, but when I installed 10.04.2 LTS the new version of TVTime had video and no sound (like everyone else here). First open TVTime (make sure the volume is up enough), then open your sound mixer. If you are like me, you'll have to install one. I chose "Gnome ALSA Mixer". You may get errors when you run it, but you can ignore them (it still works fine). Simply push the sliders up one at a time until you hear the sound from the TV. Obviously make sure nothing has mute selected (except PC speaker).

I actually fixed mine from the command line with the bogus ALSA mixers Lucid installed, but I went back and did it as described above to make it easier to explain and for you to do. My speakers have a strange plug setup. It turned out I needed to turn up the mic to hear it. Go figure...

and when the key + and - is pressed the slide will go up and down, if still no sound is because the mixer=device:channel is for OSS, the ALSA way is device/channel but I do not know yet what is the equivalent, because the path needs / and also the separator between device and channel.

later: I found that xfce4-mixer allowed me to turn on sound, making the above obsolete. But now I can't get it to load. I am getting:

xfce4-mixer: Failed to initialize xfconf: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

I have screwed up my kmixer volume control and need to tweak it. Anybody know how to fix this?
